Change History (most recent first):
|
|||
|
|
|
|||
|
|
<SM6> 12/13/93 PN Roll in KAOs and Horror changes to support Malcom and AJ
|
|||
|
|
machines
|
|||
|
|
<SM5> 9/2/93 SKH Update from Horror.
|
|||
|
|
<SM4> 2/11/93 CSS Update from Horror. Comments follow <H5-H2>:
|
|||
|
|
<H5> 11/9/92 ag Corrected compare statement. The compiler generated a long
|
|||
|
|
compare, so we must type cast the value to avoid the mismatch in
|
|||
|
|
types.
|
|||
|
|
<H4> 6/30/92 ag Use cpu info tables for configuring cpu dependent information.
|
|||
|
|
<H3> 4/24/92 ag added support for error returns on hardware initialization.
|
|||
|
|
this will return an open error on unknown hardware.
|
|||
|
|
<H2> 8/5/91 SWC Make InitPWMControls the default init choice in DRVROpen so that
|
|||
|
|
proc vectors are always initialized.
|
|||
|
|
<12> 3/30/92 JSM Rolled this file into SuperMario project.
|
|||
|
|
<11> 3/24/92 JSM Nuke boxFlag codenames.
|
|||
|
|
<10> 3/23/92 JSM OSEvents.h is obsolete, use Events.h.
|
|||
|
|
<9> 10/28/91 SAM Rolled in Regatta file.
|
|||
|
|
|
|||
|
|
Regatta Change History:
|
|||
|
|
|
|||
|
|
<9> 8/19/91 SAM <EFBFBD>unused<EFBFBD> and unused local var in Prime.
|
|||
|
|
<8> 8/19/91 SAM (ag) Removed async bit clear
|
|||
|
|
<7> 8/8/91 SAM (ag) fixed backlight driver to handle new box flags.
|
|||
|
|
<6> 7/30/91 SAM (ag) fixed low power dimming code in software only controls.
|
|||
|
|
<5> 7/18/91 SAM (ag) convert async calls to sync calls, use box flag to determine
|
|||
|
|
hardware.
|
|||
|
|
<4> 6/30/91 SAM Merged from TERROR [<10><11><12><13>].
|
|||
|
|
<3> 6/14/91 SAM (ag) added init of backlight in open. fixed initialization code.
|
|||
|
|
passin new initializtion value which will tell the hardware
|
|||
|
|
specific code to initialize. Changed low power handling code,
|
|||
|
|
and added version number function in status. Reduce power on
|
|||
|
|
non-flybywire controlled hardware during low power.
|
|||
|
|
<1> 5/15/91 SAM Split off from TERRORProj.
|
|||
|
|
|
|||
|
|
Terror Change History:
|
|||
|
|
|
|||
|
|
<13> 6/26/91 ag added support for table change as a function of charger and
|
|||
|
|
voltage.
|
|||
|
|
<12> 6/25/91 ag removed unused local variables.
|
|||
|
|
<11> 6/25/91 ag cleaned up vbl task.
|
|||
|
|
<10> 6/24/91 ag Cleaned up low power handling. Added support for version status
|
|||
|
|
call, and table switching call.
|
|||
|
|
<9> 6/11/91 ag reduce power on non-flybywire controlled hardware during low
|
|||
|
|
power.
|
|||
|
|
<8> 6/10/91 ag Changed low power handling code, and added version number
|
|||
|
|
function in status.
|
|||
|
|
<7> 5/10/91 ag fixed initialization code. passin new initializtion value which
|
|||
|
|
will tell the hardware specific code to initialize.
|
|||
|
|
<6> 4/23/91 ag added init of backlight in open.
|
|||
|
|
<5> 4/2/91 ag restructed driver for hardware independence.
|
|||
|
|
<4> 3/19/91 ag change id of portable from gestalt call to rombase call.
|
|||
|
|
<3> 3/19/91 ag Changed pram location of backlight setting to match the new parm
|
|||
|
|
layout.
|
|||
|
|
<2> 3/3/91 ag changed base of pram locations, cleaned up open code, set error
|
|||
|
|
on fly-by-wire illegal selectors.
|
|||
|
|
<1> 1/23/91 ag first checked in
|
|||
|
|
<19+> 12/18/90 ag code cleanup
|
|||
|
|
|
|||
|
|
<2> 8/19/91 JSM Use PmgrBase defined in PowerMgr.h, replace some defines with
|
|||
|
|
ones already in Power.h.
|
|||
|
|
<19> 11/13/90 ag fix for ROM power manager changes
|
|||
|
|
<17> 11/9/90 ag changed default value
|
|||
|
|
<16> 11/9/90 ag changed default to off
|
|||
|
|
<15> 11/9/90 ag fixed low power vbl stuff, changed multiplier in strobe routine.
|
|||
|
|
<14> 11/8/90 ag change the storage method for the backlight value. the 5 bits
|
|||
|
|
will now store the value of the backlight +1. the +1 offset
|
|||
|
|
allows us to detect the first boot condition. on the first
|
|||
|
|
boot, the pram will be initialize to default conditions, which
|
|||
|
|
is 0 the backlight pram location. the macros have been adjusted
|
|||
|
|
to handle the offset invisable to the routines.
|
|||
|
|
<13> 90/11/07 ag fixed bug with precheck of ram disk (include current disk )
|
|||
|
|
<11> 9/26/90 ag added change to set pot at ABSOLUTE minimum if backlight is set
|
|||
|
|
to off. added remove code to close call.
|
|||
|
|
<10> 9/25/90 ag added universal support for different version of the backlight.
|
|||
|
|
<9> 9/12/90 ag Added support for addition Control and Status calls. Now
|
|||
|
|
installs a shutdown task to turn off the backlight on showdown
|
|||
|
|
and restart.
|
|||
|
|
<8> 8/29/90 ag added support for backlight table lookup instead of straight
|
|||
|
|
values.
|
|||
|
|
<7> 8/23/90 ag fixed key equivalent bug in driver.
|
|||
|
|
<6> 8/22/90 ag added status & control calls, added dynamic maximum handling
|
|||
|
|
90/08/22 ag added additional control and status calls
|
|||
|
|
added dynamic maximum handling
|
|||
|
|
<3> 8/15/90 ag adding range feature to status call
|
|||
|
|
90/08/01 ag adjust for CCFL backlight, pot adjust from 0 - 62
|
|||
|
|
90/07/27 ag changed for fit the 3.0 c compiler and include files
|
|||
|
|
90/07/20 ag changed the name and sense of vbl semaphore (now vbl_ok)
|
|||
|
|
changed universal routines to macros
|
|||
|
|
90/03/14 ag new today
